The 36-year-old pop star dressed up like a sexy cowgirl for a holiday party on Friday. Aguilera went braless in a black embroidered jacket by Nudie's Rodeo Tailors that opened to reveal part of her chest, including a red nipple pasty, a black cowboy hat and black pants. She also wielded a pistol prop.

Aguilera posted a photo and video of her in her racy outfit on Instagram.
